The invention, in a preferred form, is illustrated in the drawings andhereinafter more fully described;

As shown in the drawings: The reference numeral lOindica-tes genaportion of the chassis or-iraine of an automobile of the usual channeledconstructio A bumper comprising mainly a transv'. 9 extending bar 12 18adapted to be an lied to the chassis or frame member 10,

s best shown in Figure 1, the ends of the bar 12 are bent rearwardly andthence inwardly to form a rounded end, the inwardly extending portion asillustrated at being substantially parallel to the main portion of thebar 12.

A suitable opening is pi'ovidlecl in the enol oijthe inwardly bentportion 14 and through this opening is passed a bolt 16 provided withsuitable washers i8 uncle retaining nut 20 which bolt also passesthrough a corresponding opening in :1 short member 22 formed in a zigzagshape as best illustrated in Figure 1, having its other end adapted toco-operate with a section of the main bar 12.

Fittecl between the inner encl of the zigzag member 22 and a cooperatingportion of the main bar 12 is the encl of {in-extending arm 2% which isadapted to supportthe bumper in position. Suitable retaining means inthe form of abolt 26 are provided at this point and the bolt passesthrough proper openings in the ends of the member 22, the supportingelement and in the main bar'l2.

The rearward end of the supportinj or extending member 24 is preferablyent downwardly as best illustrated. at 28 110. Figure 2, ancl is fittewith a number of 0 nings; One of these openings is provide at a pointclosely approximating the beginning of the downwardly bent portion 28and is adapted for the reception of a bolt or the like 30 as bestillustrated in Figures 1 and 3, which bolt is fitted with a retainingnut 32 and a suitably shaped sleeve 34, the construction ofwhich is bestillustrated in the broken away portions in Figure 3.

Ada ted to co-operate with this sleeve-34 and with the bolt 30 is aclamping element 38 bent as shown in Figures .3 and 5, the upperextension of which is adapted to cooperate with a correspondinglyinclined wedge face of the sleeve member 34 and the lower extension ofwhich is adapted to reach under and firmly clamp against the under faceof the channeled member 10 forming partof the automobile chassis. Asuitable squared opening 40 is provided in the clamping member adaptedfor the reception of the correspondingly squared shank portion of thebolt 30. i

The downwardly extending portion 28 of the sup orting element 24 isfitted with a series 0 openings as best illustrated at .42

in Figure 2 and through any one of these openings is adapted to pass abolt 44 fitted with a sleeve 34 and a clamping element 38 as has alreadybeen described in conjunction with the bolt 30. It will be evident thatthe positioning of the bolt 44 in any one of the series of holes 42 willresult in a corre-,

sponding raising or lowering of the bumper 12. whereby the height andrelation of the bumper with'respect to the automobilemay be accuratelyadjusted as desired.

A slight modification of the clamping de'- vice is illustrated inFigures 4 and 6 wherein the bolt 30' ,is; formed with a squared head 46,the head itself being adapted to contact with the modified clampingmember as illustrated at 48 and which comprises in this instance merelya V-shaped member as illustrated, having a circular opening 50 in one ofthe sidesthereof. The bearing sleeve ada ted to surround the bolt 30 isformed wit amore angularly inclined end as illustrated at 52 for properwedging contact with the inner face of the mem er 48. The

lower end of this member fits under and.

grips the channeled frame member 10 in the manner illustrated in Figure4. v

It will beseen that herein is provided an automobile bumper of simpleyet strong and durable construction, and which is composed of a minimumof parts, and there- I fore not likely to work loose, rattle, or get outof order.

Further, the attaching means particularly provide a simple method ofpositively affixing the bumper to the automobile chassis,

and without the use of any special tools, and

made and' numerous details of construction varied throughout a widerange without departing from the principles of this invention, and Itherefore do not purpose limiting the patent granted hereon otherwisethan as necessitated by the prior art.

I claim as my invention:

1. An automobile bumper, including in combination, a transverselyextending bar, each end-of said bar being bentgearwardly and thenceinwardly in parallel relation to the main portion of said bar, bracingelements afiixed to the end of each of said inward extensions, each ofsaid bracing elements comprising amember having offset ends, one of saidends attached to said in-- wardly extending end and the other endadapted to co-operatewith the main portion of the bumper bar, and meansco-operating with the bracing elements for attaching the bumper to anautomobile.

I 2. An automobile bum er, including in combination, a transverse yextending bar, each end of said bar being bent rearwardly and thenceinwardly in parallel relation to the main portion of said bar, a bracingelement aflixed to the free end of said in ward extension, said bracingelement comprising a member having ofiset ends, one of said endsattached to wardly extending end and the other end adapted to co-o cratewith thermain portion of t e bumper ar, and means for attaching thebumper to an automobile, said means comprising a sup ort member aflixedto the bumper at the unction of the aforesaid bracing means with thebumper.
